K01 Synthetic Health Data

K01 MCP Server

Generate and query clinically realistic synthetic health data directly from your AI workflow.

---

K01's MCP server gives AI agents and LLM-powered tools access to privacy-preserving synthetic health data generation. Generate FHIR-compliant patient cohorts, query structured EHR data, and compare across FHIR versions — all with built-in differential privacy. No real patient data is involved at any point.

This repository contains documentation and configuration for the K01 MCP server. The server implementation is proprietary and runs on K01 infrastructure.

Available Tools

Tool	Description	Key Parameters
generate_synthetic_cohort	Generate synthetic patient cohorts with demographic and clinical constraints	count, age_min/age_max, gender, condition (ICD-10), seed, locale
search_patients	Search a virtual patient database with advanced healthcare filters	gender, birthdate, numberOfMedicinesFrom/To, conditionTypes, locale
get_patient_record	Retrieve a complete patient record with medication and condition summaries	patient_id, fhir_version
get_patient_medications	Get detailed medication records with ATC codes and therapeutic indications	patient_id, seed, fhir_version
get_patient_conditions	Retrieve patient conditions with ICD-10 codes and localized names	patient_id, seed, fhir_version
compare_fhir_versions	Compare the same patient data across FHIR R4 and R5	patient_id, resource_type

All tools support both FHIR R4 and R5. See docs/tools.md for full parameter documentation.

Quick Start

Claude Desktop

Add to your Claude Desktop configuration (Settings > MCP Servers):

{
  "mcpServers": {
    "k01": {
      "url": "https://mcp.k01.is/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Cursor

Add to your Cursor MCP configuration (.cursor/mcp.json):

{
  "mcpServers": {
    "k01": {
      "url": "https://mcp.k01.is/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Restart the application after adding the configuration. The K01 tools will appear in the tool list.

Authentication

The K01 MCP server uses Bearer token authentication. Include your API key in the Authorization header.

To get an API key, contact K01 at k01.is. Self-service key provisioning is coming soon.

See docs/authentication.md for details.

Examples

Generate a diabetic cohort

"Generate 100 patients aged 40-65 with Type 2 diabetes"

The generate_synthetic_cohort tool creates a FHIR Bundle with Patient, Condition, MedicationStatement, Procedure, and Observation resources:

generate_synthetic_cohort(count=100, age_min=40, age_max=65, condition="E11.9", seed=42)

Search for complex patients

"Find patients with 3+ medications and chronic conditions"

search_patients(numberOfMedicinesFrom=3, conditionTypes="chronic", _count=20)

Compare FHIR versions

"How do this patient's medications look in R4 vs R5?"

compare_fhir_versions(patient_id="0101302989", resource_type="Medication")

See docs/examples.md for more workflows.

Privacy and Security

All data generated by K01 is fully synthetic. No real patient data is used, stored, or referenced at any point in the pipeline.

• Differential privacy — noise injection with configurable epsilon values ensures generated distributions cannot be reverse-engineered to identify real individuals
• No training on real data — the generation models are built from published clinical statistics and pharmacological references, not patient records
• FHIR-compliant output — all resources conform to HL7 FHIR R4/R5 specifications, making them safe drop-in replacements for real data in development and testing
• Deterministic seeding — use seeds for reproducible results without persisting any patient data server-side
